Oracle Database 10g R2: Administering RAC Sample Questions:
1. In which directory should you put your callout scripts on your RAC nodes?
A) $ORACLE_HOME/opmn/conf/
B) $ORA_CRS_HOME/opmn/conf/
C) JORACLE_HOME/racg/usrco/
D) $ORA_CRS_HOME/racg/usrco/
2. You are asked to justify your proposed Maximum Availability Architecture to the IT director who feels that a four-node RAC cluster on the primary should not require a four-node RAC cluster for a physical standby database. The director suggests that either a non-RAC database should be used on the standby or that at most a two-node cluster is all that is required. Your proposed architecture was designed for both planned and unplanned downtime and for performance and scalability of services for all eventualities. How would you justify your proposal? (Choose two.)
A) The four-node physical standby database provides for continuous availability of services but the two-node RAC physical standby database does not.
B) A non-RAC physical standby would not provide for high availability in the case of a lights out failover to the standby.
C) A two-node physical standby would not allow as many services to be supported as a four-node physical standby does in case of a failover to the physical standby.
D) Asymmetric configurations prevent the standby from issuing a FLASHBACK DATABASE command if required after a failover.
E) The four-node physical standby provides for the same service preferences and performance profile in case of a failover to the physical standby database.
3. Which three statements about Snapshot Control File Management in a RAC environment are true? (Choose three.)
A) By default, the snapshot control file is created on the node that is making the backup.
B) You need to configure a default path and file name for these snapshot control files that is valid on every node from which you might initiate an RMAN backup.
C) RMAN parameters controlling snapshot control files can be configured from the Enterprise Manager Cluster Database home page.
D) You can use a cluster file system or a raw device to store snapshot control files.
4. Which two statements are true in any RAC environment? (Choose two.)
A) A publicly enabled thread can be used by any instance of your RAC database.
B) A RAC database must contain at least two threads of redo log files per instance.
C) A RAC database must contain at most one redo thread for each instance.
D) After your redo threads are defined, you cannot add new ones.
E) A redo thread must contain at least two groups of redo log files before it can be enabled.
5. Which three statements about patching Oracle products in a clustered environment are true? (Choose three.)
A) The Oracle Universal Installer (OUI) is cluster-aware and able to manage patches on all nodes in your cluster.
B) OUI prevents potentially destructive concurrent patch installations through the use of Inventory List Locks.
C) OUI manages patches in a clustered environment only if a shared ORACLEJHOME is employed.
D) The OUI automatically manages the patch installation progress, including the copying of files to remote nodes, just as it does with the CRS and database binary installations.
